Orientifold and Integrability: Super-Yang-Mills on

Joao Caetano, Shota Komatsu, Paolo Soresina +1

We study planar super Yang-Mills theory (SYM) on the real projective space using integrability, holography and supersymmetric localization, and disc…

Matrix Theory from Holography

Shota Komatsu, Eunwoo Lee, Chintan Patel

We propose a setup that embeds Matrix Theory for M-theory into the AdS/CFT correspondence, allowing the former to be tested using the latter. The central claim is a triality among…

Time-Dependent Integrability from Gauge Theory, I

Shota Komatsu, Jun-ichi Sakamoto, Anders Wallberg +1

Solvable time-dependent systems provide important settings for studying non-equilibrium physics, where exact results are rare. They are also useful for benchmarking quantum simulat…

Crosscap Defects

Nadav Drukker, Shota Komatsu, Anders Wallberg

We introduce a novel class of defects, termed crosscap defects, in conformal field theory (CFT) in general dimensions. These arise from quotienting the spacetime by a automor…

Continuous Family of Conformal Field Theories and Exactly Marginal Operators

Shota Komatsu, Yuya Kusuki, Marco Meineri +1

Does a conformal manifold imply the existence of exactly marginal operators? We answer this question affirmatively under the assumption that there exists a conformal interface with…

Dressing and Screening in Anti-de Sitter

Ankur, Lorenzo Di Pietro, Victor Gorbenko +2

Motivated by a question of defining gauge-invariant observables in cosmology and by the close connection between perturbation theory in de Sitter (dS) and Anti-de Sitter (AdS), we…

F-theorem for Quantum Field Theories in Anti-de Sitter Space

Davide Bason, Christian Copetti, Lorenzo Di Pietro +2

We introduce a regularized free energy for massive quantum field theories (QFTs) on Anti-de Sitter space (AdS). We conjecture this quantity to be monoton…

Chiral Composite Linear Dilaton as String Dual to Two-Dimensional Yang-Mills

Shota Komatsu, Pronobesh Maity

Two-dimensional Yang-Mills theory (2d YM) is arguably the simplest confining gauge theory and its large expansion has a structure of the genus expansion in string theory. Nev…

Worldsheet for Generalized Veneziano Amplitudes

Shota Komatsu, Pronobesh Maity

We present a worldsheet action that reproduces a class of dual resonance amplitudes discussed in the literature, which generalize the Veneziano amplitude for open strings. Our prop…

String Duals of Two-Dimensional Yang-Mills and Symmetric Product Orbifolds

Shota Komatsu, Pronobesh Maity

We propose a bosonic string dual to large chiral Yang-Mills in two dimensions at finite 't Hooft coupling. The worldsheet theory is a - system deformed by a chiral Polchi…

Coulomb Branch and Integrability

Frank Coronado, Shota Komatsu, Konstantin Zarembo

We study one-point functions of non-BPS single-trace operators on the Coulomb branch of planar supersymmetric Yang-Mills theory. Holography relates them to overlaps…

Exact Three-Point Functions in Superconformal Field Theories: Integrability vs. Localization

Gwenaël Ferrando, Shota Komatsu, Gabriel Lefundes +1

We propose an integrability approach for planar three-point functions at finite coupling in superconformal field theories obtained as orbifolds of $\…

Strings from Feynman Diagrams

Rajesh Gopakumar, Rishabh Kaushik, Shota Komatsu +2

For correlators in Super Yang-Mills preserving half the supersymmetry, we manifestly recast the gauge theory Feynman diagram expansion as a sum over dual closed str…

Einstein gravity from a matrix integral -- Part II

Shota Komatsu, Adrien Martina, Joao Penedones +2

Using supersymmetric localization, we compute the partition function and some protected correlators of the polarized IKKT matrix model. Surprisingly, we find that the original IKKT…

Einstein gravity from a matrix integral -- Part I

Shota Komatsu, Adrien Martina, João Penedones +2

We construct backreacted geometries dual to the supersymmetric mass deformation of the IKKT matrix model. They are Euclidean type IIB supergravity solutions given in terms of an el…

S-Matrix Bootstrap and Non-Invertible Symmetries

Christian Copetti, Lucia Cordova, Shota Komatsu

We initiate the S-matrix bootstrap analysis of theories with non-invertible symmetries in (1+1) dimensions. Our previous work showed that crossing symmetry of S-matrices in such th…

2d QCD and Integrability, Part II: Generalized QCD

Federico Ambrosino, Shota Komatsu

We extend the study of integrable structures and analyticity of the spectrum in large QCD to a broad class of theories called the generalized QCD, which are given by the…

Vacuum Condensates on the Coulomb Branch

Vyacheslav Ivanovskiy, Shota Komatsu, Victor Mishnyakov +3

We study correlation functions on the Coulomb branch of planar super-Yang- Mills theory (SYM), and their relationship with integrability, the operator product exp…

Non-Invertible Symmetries, Anomalies and Scattering Amplitudes

Christian Copetti, Lucia Cordova, Shota Komatsu

We show that crossing symmetry of S-matrices is modified in certain theories with non-invertible symmetries or anomalies. Focusing on integrable flows to gapped phases in two dimen…

We revisit the Berenstein-Maldacena-Nastase (BMN) conjecture relating M-theory on a PP-wave background and Matrix Quantum Mechanics (MQM) of matrices. In particular, we…
